Of course you will need a map to help navigate your way around the sprawling city. Depending on the maker of your Smartphone, you might be able to find an app at iTunes. Not sure of the status of the app that guides users away from, ahem, high-crime areas, but you might want to use a map that helps guide you to Bronzeville, one of the oldest African-American neighborhoods in the nation that was once home to Louis Armstrong, civil rights leaders Ida B. Wells, and Bessie Coleman. Another stop could be a visit to the Hyde Park neighborhood of the Obamas. While the home is heavily guarded, it might be worth catching a glimpse of the modest, yet well-appointed grounds.
